if the actual requirement is always same.. then you can replace "java" with "java is language".

Code:
echo "java code" | sed 's/java/java is laguage/1'

If there's only one line in the file, there's no need for an external program:

Code:
file=x.txt
IFS= read -r line < "$file"
right=${line#*java }
left=${line%%"$right"}
echo "$left is language $right"

no ....file contains multiple line of code...

but in SED solution i store the updated file at same location so if i run it twice.
i.e.
replace "java" with "java is language".

it wil screw up that file with multiple copies....

so both above solutions r not working !!

what to do ?

hi all ,
java is lanaguage...
yes i think it is
so shell script is very powerful
java is good for platform independence projects
i want output as :
Quote:
hi all ,
java AA is lanaguage...
yes i think it is
so shell script is very powerful
java AA is good for platform independence projects
if i run ur command twice it should not effect the output. (keeping in mind..resultant file should be same as source file)

In the first run a normal "sed" will solve your problem. But in the second run obviously the search pattern will be replaced since it is a successful search.

Can You tell what your real requirement is , so can check for alternates.
